INTRODUCTION
These instructions cover the installation, operation
maintenance of an EACB Electronic Air Cleaner.
and
This electronic air cleaner is technically known as a two--stage
electrostatic precipitator. The air cleaner is designed to remove
airborne particulates, including dust, dirt, smoke, pollen, virus,
spores, bacteria and mold, from indoor air. Air movement through
the unit is provided by the heating, air conditioning or ventilating
system blower. As dirty air enters the air cleaner, the air passes
through a metal mesh prefilter. The prefilter prevents lint, pet hair
and other large particulates from entering the air cleaner. It is
important that these filters be in place to prevent excessive dirt
loading of the air cleaner collector cells. These filters extend the
time between maintenance of the air cleaner collector cells. This
allows the ionizing--collector cells to provide clean air for a longer
period between washings. The prefiltered air then passes through a
two--stage Electronic Air Cleaner. In the first stage, all airborne
particulate, even submicron size, are electronically charged
(positive) as they pass through the ionizer. The ionizer field is set
up by a corona discharge emanating from the fine, tightly strung
wires suspended between two adjacent flat plates. In the second
stage, the charged particulate passes through an intense electrical
field established between alternately charged and grounded parallel
collector plates. Here, the positively charged particulate is attracted
to the negatively ground plates and removed from the air stream.

AirFlow Sensor (AFS)
this cooling down effect allows the electronic AFS to understand
that the furnace blower is moving air and the Electronic Air
Cleaner must turn on to provide air cleaning.
This part controls the operation of the unit by sensing the
movement of air within the duct. This helps to reduce power usage.
How to Identify Which Air Cleaner Model You Own
The model number and serial number for your Electronic Air
Cleaner can be found on the data label located on the inside of the
access door.
Facts You Should Know About Your New
Electronic Air Cleaner
If the air cleaner is installed in a location that is dusty and dirty, the
sensor on the AFS can become coated with dirt and lint. This
coating can insulate the AFS and keep it from operating properly.
To clean the thermistor, turn unit off and allow thermistor to cool,
then take a cotton swab dipped in rubbing alcohol and carefully
insert it into the hole located on the right hand side of the power
pack assembly (when facing the unit). The hole is 3/16” (5 mm) in
diameter and is located on the front of the power tray assembly.
Carefully twirl the cotton swab between your fingers, making sure
the tip is lightly in contact with the coated bead, cleaning this
coating from the thermistor. If airflow sensor is bypassed on the
circuit board, the Air Cleaner will run at all times when power is
applied (see Fig. 4).

Outdoor Air
When outdoor air is added to the return air duct, sufficient heat
should be added to maintain the return air temperature at 55_F
(13_C) intermittent or 60_F (16_C) continuous. Lower air
temperatures can cause premature heat exchanger or ionizer wire
failures.

CAUTION
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when
handling these parts.
How the AirFlow Sensor (AFS) Works
Electronic AFS (see Fig. 3) was designed to provide an efficient
and reliable method of controlling the operation of the air cleaner
when the dealer is unable to wire the unit directly into the furnace
blower. The electronic AFS is now integrated into the power
supply circuitry and utilizes a thermistor that heats up to
approximately 130_F (54_C). The AFS then stabilizes at this
temperature and when the furnace blower turns on and air flows
through the ductwork, the same vacuum effect pulls cooler air over
the hot surface. This air movement cools down the thermistor and
AIRFLOW SENSOR
BYPASSED
The Electronic Air Cleaner is adaptable to all new or existing
residential forced air furnace and cooling systems.
Transitions
If the air duct does not fit the air cleaner cabinet opening, gradual
transitions (see Fig. 5) are recommended to reduce air turbulence
through the air cleaner and maximize efficiency. Not more than
20_ (about 4” / 102 mm per running foot / 305 mm) of expansion
should be used on each side of the transition fitting.

EACB
Dusting and “White Dust”
Your new Electronic Air Cleaner will efficiently clean and filter
your household air. Unfortunately, it will not eliminate the need for
regular dusting of your furniture and belongings. Due to the design
of all duct--mounted air cleaners, they can only clean the air that
reaches the air cleaner. Therefore, if the particulates are not being
carried to the air cleaner in the air stream, the air cleaner cannot
remove them from your home. Occasionally a “white dust” may be
noticed in bedrooms or newly furnished rooms. This is mainly
composed of lint which, because it is heavier than other
particulates, settles before it reaches your unit. This “white dust” is
not mixed with airborne dirt particles, therefore, it is clean and has
no staining or soiling properties. However, running the furnace
blower continuously, day and night, will help reduce this from
occurring.
Ozone
Under normal operating conditions all Electronic Air Cleaners
produce minute quantities of ozone as an incidental by--product. In
fact, all electronic products, such as televisions, cordless phones
and refrigerators, produce some amount of ozone. The average
homeowner can detect the smell of ozone concentrations as low as
25 to 100 ppb (parts per billion). The design of this unit has been
tested and ozone production is approximately half of the published
permissible limits established by the Environmental Protection
Agency. These limits recommend that the concentration of indoor
ozone not exceed 50 ppb. Ozone is not harmful in these
concentrations. In fact, the ozone level in major cities can
sometimes reach as high as 100 ppb on a summer day. The
addition of optional charcoal after--filters can help reduce this.
Normally, a new unit will produce more ozone than one that has
been in operation for several weeks. This is due to sharp corners or
manufacturing burrs on the ionizing--collecting cell(s) and is
normal. As the Electronic Air Cleaner arcs and zaps, the voltage is
vaporizing these areas and tends to round them off. This is part of
the breaking--in period of ownership and the issue is
self--correcting. Also, high--altitude locations can be more
susceptible to noticing the presence of ozone. An
ionizing--collecting cell that has been damaged or bent (the
designed spacing between electrically charged and ground
components has been decreased) may also produce an abnormal
amount of ozone.

Application
AIR FLOW
Air cleaners are used in forced air heating cooling and ventilating
systems. The air cleaner should be installed in the system so that all
the system air is circulated through the air cleaner. The air cleaner
will only remove the airborne contaminants delivered to it.
Maximum performance is obtained when the system blower is set
for continuous operation.

Do not install the air cleaner in the discharge air duct.
Turning Vanes
If the air cleaner is installed adjacent to a 90_ duct elbow, add
turning vanes (see Fig. 6) inside the duct to improve air
distribution across the face of the air cleaner. Failure to follow this
recommendation can reduce the efficiency of the Electronic Air
Cleaner.
Before installing the air cleaner, consider the application and type
of HVAC system present. See Fig. 7 for the most common types. If
a transition between the ductwork and air cleaner is required, refer
to section entitled Transitions and Fig. 5. The unit must be readily
accessible for periodic inspection and cleaning of the prefilters and
electronic cells to maintain maximum efficiency and trouble--free
operation.
Air Conditioning
The air cleaner should be installed upstream of the cooling coil.
This will keep the coil clean and reduce air conditioning coil
maintenance. Improved cooling efficiency is the result and directly
affects energy costs. A clean coil will reduce utility costs.

COMMONLY ASKED QUESTIONS
Q. Why isn’t my air cleaner cleaning my air?
A. The air cleaner is most likely working just like it was designed.
However, many factors can affect the performance of the unit. Are
cold air registers located in the ceiling? If so, it will be difficult for
the airflow to carry heavier particulates to the air cleaner. If the dirt
doesn’t get to the air cleaner, it can’t be removed from the air. Are
both the Red and Green lights illuminated? If not, then the unit
may be in need of servicing. Contact your local HVAC dealer for
assistance.
Q. It still isn’t cleaning my air the way I want it to. What can I
do?
A. We recommend that you run the blower continuously so that
the air movement will carry the dirt to the air cleaner.
Unfortunately, there will always be some dirt that is left behind on
the appliances, furniture, etc. Regular dusting is recommended to
stir up these pockets of dust so that they can enter the airstream and
be removed by the Electronic Air Cleaner.
Q. When I turn on my Electronic Air Cleaner, the lights come
on for a couple of seconds and then turn off. The air cleaner
isn’t working!
A. The air cleaner is fine as long as both the Red and Green lights
are coming on. Try turning the HVAC blower OFF and then
turning the Electronic Air Cleaner on. This should solve the
problem.
Q. What is the zapping noise I am hearing from my unit?
Should I be concerned?
A. The zapping or popping noise that you are hearing is the sound
of larger particles being vaporized by the ionizing--collector cell.
This is normal and is no cause for alarm. As your HVAC system
blower moves the air through the ductwork and allows the
Electronic Air Cleaner to clean the air, the noise will diminish.
However, there will always be instances when larger particles enter
the ionizing--collector cell.
Q. Should I hear this zapping noise all the time?
A. All Electronic Air Cleaners will occasionally zap or pop as
larger particles pass through the ionizing--collector cells. However,
if the sound is constant or is repetitive in nature, then a large
particle may have become lodged in the ionizing--collector cells
and they may require cleaning. If cleaning the ionizing--collector
cells does not stop the noise and there are no large particles trapped
in the ionizing--collector cells, then the cause could be a
broken/loose ionizing wire, bent collector plate or other mechanical
reason. Please contact your local HVAC dealer for assistance.
Q. What if I no longer hear any popping or zapping noises
coming from my unit? Is it still cleaning the air?
A. If the zapping noises stop and the air cleaner is not in need of
servicing, then one of two situations has occurred. First, the
Electronic Air Cleaner has successfully removed all larger particles
from the air and is cleaning microscopic particles which do not
cause the zapping noise. Second, the blower and/or HVAC system
is not running and air is not flowing through the ductwork. The
Electronic Air Cleaner cannot remove particles if the air stream is
not moving.
Q. I lost power to my home during a storm. Should I worry
about the Electronic Air Cleaner?
A. The most common problem associated with power outages is
the unit will not turn on properly after power is restored. If the Red
and Green light come on for a couple of seconds and then go off,
the unit is OK. Just turn the HVAC blower off, turn the unit ON
and then turn the blower back on. If the Red and/or Green light
does NOT come on after a storm, the power supply in the
Electronic Air Cleaner may be short circuited. Contact a local
HVAC contractor for further information.
Q. My installer told me to keep the HVAC system blower
running all the time, but I don’t want to increase my power
bill. What should I do?
A. It is recommended that you keep your HVAC system blower
running all the time to achieve the maximum air cleaning
efficiency. This will allow the Electronic Air Cleaner to do what it
is designed to do, which is clean the air. Remember that if the air
does not reach the air cleaner, it cannot be cleaned. On average,
your Electronic Air Cleaner will use the same amount of electricity
as a 55 watt light bulb. The energy usage of the HVAC system
blower will depend on the age of your system, energy costs in your
regional location and other variables. The best solution is to try
running the HVAC system blower in continuous mode for a month
or two to estimate your annual energy costs and base your final
decision on what you feel most comfortable with.

MAINTENANCE OF CELLS
TROUBLESHOOTING
EACB
Washing Cells and Prefilters
!
Regular washing is necessary to ensure proper performance (see
Fig. 11). A thorough washing once every two months will be
adequate for most installations. More frequent washing (once a
month) may be necessary on some installations (new homes for
example) where there is new carpeting, plaster dust, or excessive
cigarette smoke.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
The following procedures could expose hazardous live
components. Only a trained, experienced service person
should install this electronic air cleaner. When the circuit has
been de--energized, always discharge any residual current in
the secondary with an insulated handle screwdriver. Always
ground power supply and ionizing--collecting cell when bench
testing. Before performing installation, service or maintenance
operations on unit, turn off all power to unit. TAG
DISCONNECT SWITCH WITH LOCKOUT TAG.
To remove cells and prefilter
1. Push air cleaner switch to the OFF position. Wait 15
seconds. Open door access panel.
2. Carefully remove cells and prefilter(s) and set aside in a safe
place.
3. Do not drop the ionizing--collector cell. This could cause
damage to the cell plates or ionizing wires and cause
excessive arcing and noise.
To wash cells and prefilter(s)
To wash cells and prefilter(s) We suggest that you follow the
instructions below to properly and thoroughly clean your collector
cells.
1. Place enough hot water in a utility tub to cover the first cell.
Dissolve 2 to 4 oz. of granulated automatic dishwasher
detergent (not laundry detergent) in the water.
2. Allow the cell to soak for 30 minutes. Agitate it up and
down in the solution until it appears clean and remove.
3. Repeat with second cell.
4. Agitate the prefilters up and down in the solution until they
appear clean.
5. With a hose, rinse the cells and prefilters. The hose should
be held about 10” (254 mm) from the cell plates and at a
slight angle for better cleaning results. Be careful not to
spray the ionizing wires directly with the hose. The water
pressure can cause the wire to snap and break. The cell
frame should be thoroughly rinsed along the edges to
dislodge any trapped lint or dirt. Carefully wipe a damp
cloth or sandpaper (not emery cloth) along the ionizing
wires.
6. Stand cells and prefilters up to drain. Let dry two hours.
You may experience a slight discoloration of the aluminum
collector cells after washing. This is a normal chemical
reaction and will not harm your unit or affect its
performance.
To replace cells in air cleaner
1. Replace prefilter and cells in cabinet. Check that arrow on
cells points in same direction as air flows through the duct
(If you have to force it past the positioning screw on
bottom, it is probably in the wrong position).
2. Replace access door (engage tabs on lower edge of door
into slots in cabinet). Carefully close door.
3. Turn air cleaner switch to ON.
WARNING
Recommended Service Tools
1. Screwdriver, 8” common with insulated handle (plastic)
2. Screwdrivers Phillips #1 and #2 with plastic insulated
handles
3. Needle nose pliers
4. Multimeter
5. High voltage probe
Indication of Electrical Trouble
The air cleaner is equipped with a Red CELL ENERGIZED light
for indicating proper unit operation. When the unit is in normal
operation (with the HVAC system fan running, access door in place
and rocker switch in the ON position) and the Red CELL
ENERGIZED light is not lit, the problem is a shorted secondary.
Although failure of the indicating light itself should not be
overlooked, this condition is unusual and rather remote.
Primary Circuit with Blower Operating
If there is supply line voltage at the connections and no input
voltage to the power supply, the outage can be located by checking
operation of the safety switch and the interconnecting wiring with a
multimeter. Refer to Circuit Diagram, to check operation of the
switches. Following these steps to test for proper operation of the
circuit board and power supply assembly:
1. Ensure that the circuit breaker controlling the furnace
blower is in the ON position and the main fuse is not open.
2. The power supply board has a built--in internal fuse to
protect the 24V transformer. It can be checked visually by
inspecting the fuse. If the fine wire inside the fuse is broken,
this indicates a problem in the 24V circuit of the power
supply board. Do NOT replace this fuse. The entire power
supply board must be replaced. The purpose of the fuse is
not to protect the power supply board, but to function as a
troubleshooting feature of the product and to protect the
transformer from damage.

Ionizing--Collecting Cell
Secondary Circuit
The cell is electrically energized through a contact terminal located
at the top center of the cell. The ionizing wires and alternating
collector plates are electrically charged while the interleaving plates
are grounded. If the space between the charged and grounded
plates is bridged with conductive or semi--conductive material, a
short circuit develops. The bridging or short may be caused by
damaged plates, or foreign material lodged between/on the
components.
Since the cell should be periodically removed from the unit to
wash away collected dirt, it is susceptible to physical damage. The
cell also contains the ionizing wires which, due to their function,
have been designed with minimal structural support and are
susceptible to breakage. However, trouble related to a shorted
collector cell is readily shown by the Red CELL ENERGIZED
light and can be quickly isolated by a simple procedure.
To determine if a short exists in one or both of the collector cells,
turn the Electronic Air Cleaner OFF and remove both electronic
cells from the cabinet. Shut the door and repower the unit. If the
Red CELL ENERGIZED light comes on, an electrical short exists
in one or both of the electronic cells. Replace the cells in the unit,
one at a time, to determine which cell is shorted. Most troubles in
the cell can be visually detected and corrected.
NOTE: The ionizer collector cells are not designed for field repair.
Ionizing wires and insulators can be field replaced. It is not
recommended that you attempt to replace other cell components
(i.e. Collector plates, end plates, ionizer supports).
Wires are supplied in a coiled spring configuration, with a clinch
nut on each end of the wire. Replacement requires a pair of needle
nose pliers. Exercise caution in removing any broken wires in the
collector cell. This will prevent accidental shorting of the cell and
reduce the need for further maintenance. Use the following
procedure when replacing an ionizing wire.
1. Ensure that all power to the Electronic Air Cleaner is OFF,
remove the access door and remove the ionizing--collector
cells from the unit.
2. Carefully remove all remains of the broken wire.
3. Grip the new wire at each end of the wire with your thumb
and index finger. While stretching the wire to approximately
6” (152 mm) allow one end of the wire to uncoil between
your thumb and index finger.
4. Place one end of the wire in the slot of the stainless steel
support on the collector cell from the front of the cell. This
support is partially covered by the cell brace in front of the
support.
5. Grip the other end of the ionizing wire with needle nose
pliers and insert the terminated end of the wire into the slot
on the support bar of the opposite end of the collector cell.
6. The wire should be tight enough to be self supporting and
remain suspended between the two support slots in the
support bar.

ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
The following procedures could expose hazardous live
components. Only a trained, experienced service person
should install this electronic air cleaner. Before performing
installation, service or maintenance operations on unit, turn off
all power to unit. TAG DISCONNECT SWITCH WITH
LOCKOUT TAG.
AFS Troubleshooting
1. Make sure the furnace blower is not operting, the rocker
switch is OFF, and the circuit breaker is turned OFF or the
cord is disconnected.
2. Remove the access door.
3. Remover power tray assembly.
4. Locate the AFS. It is the circuit board with a small gray disc
connected to the circuit board by two (2) silver wires.
Carfully bend the thermistor so that it is located in the center
of the opening and approximately 1/8” (3 mm) from the
inside edge of the power pack assembly.
5. Reinstall the power tray assembly and access door.
Replacing the Ionizing Wires
Ionizing wire breakage is minimal because of the constant tension
design and fixed location of the ionizing wire supports. When an
ionizing wire breaks, the efficiency of the Electronic Air Cleaner
will decrease slightly. However, the unit will continue to operate
with broken ionizing wires as long as the broken wires have not
caused a short circuit of the unit. Remove all loose and broken
wires as soon as they are identified. Although the replacement of
the ionizing wires can be attempted by a homeowner, it is
recommend that you should contact a qualified HVAC contractor
for replacement parts and/or servicing.
WARNING
High Altitude Operation
Because the air is less dense at higher altitudes, there is a possibility
of nuisance arcing. The homeowner can quickly and easily correct
this condition.
1. Turn the unit OFF. Turn off circuit breaker or disconnect the
power cord.
2. Remove the two screws that secure the cover to the power
tray and remove it from the unit. (The entire power supply
tray may be removed from the cabinet by removing two
screws from inside cabinet.) Do not lose these screws.

3. If the fuse is NOT blown, check the ON/OFF switches and
safety interlock switch for proper engagement and
operation. This can be completed using a volt ohm
millimeter on a scale that will measure ohms as low as 1.0.
If you are using the recommended meter previously
mentioned in this manual, set the meter to read 200 ohm
and proceed with Steps 4 through 6.
4. Remove the fuse. Connect one lead to the test pin located
directly beside the wire that connects the ON/OFF switch to
the power supply board. Connect the other lead to the fuse
connection closest to the front panel.
5. Turn the ON/OFF switch to the ON position and depress
the safety interlock switch. The meter should have the
capability of reading levels as low as 1.0 ohm.
6. If there is no reading on the meter, begin the process of
elimination by disconnecting the wire from the test point
and connecting it to the terminal with the blue wire located
on the safety interlock switch. Depress the safety interlock
switch. If the reading on the meter is greater than 1.0 ohm,
the safety interlock switch is defective and must be replaced.
If the reading on the meter is less than 1.0 ohm, the
ON/OFF switch is defective and must be replaced.
3. Locate the jumper terminal (see 12).

WARNING
4. With a pair of needle nose pliers, carfully adjust the jumper
settings from HIGH to MED. Ensure that the jumper is
firmly seated in the terminal.
5. Replace the power tray cover and secure it with the two
screws.
6. Replace the access door and turn the unit ON.
This procedure will slightly reduce the output voltage, minimize
arcing, and reduce ozone production. If the condition does not
improve, repeat the above procedure and move the jumper setting
from MED to LOW. If this does not correct the situation, contact
your local HVAC dealer. All Electronic Air Cleaners are produced
at the factory with the jumpers set in the HIGH position. However,
the output voltage may be lowered in any situation where the unit
is arcing excessively or there is excessive ozone production.
7. If no voltage is measured, remove the first cell and check
the second cell. The meter should read 6.2 kVDC ± .2
kVDC.
8. If proper voltage is measured, the first cell is shorted.
9. If no voltage is present, remove the second cell. Install cell
number one and measure voltage as described above. If
voltage is present, the second cell, which is now out of the
cabinet, is shorted.
10. If no voltage is present, remove both cells and measure the
power supply output. While drpressing the safety switch,
touch the end of the high voltage probe (see Fig. 13) to
either the front or rear contact board assembly. The meter
should read 6.2 kVDC or higher.
11. If no voltage is present, check the power supply. Set the
multimeter for reading AC voltage at 200 volt full scale and
attach meter test leads.
12. While depressing the safety lever, touch the two transformer
output lead junctions to the power supply board with the
meter leads and read the meter.
13. If there is no oputput voltage from 24 volt transformer,
replace the 24 volt tranformer and power supply board.
Checking the Power Supply
If the output light remains out with the collector cells removed
from the cabinet, the power supply is defective. Specific problems
on the power tray assembly can be isolated by using a multimeter
and high voltage probe to check the output voltages. To check the
secondary circuit, a high voltage meter is required. See the section
entitled Recommended Service Tools. To check for proper
operation, it is imperative that the procedure be followed as
outlined below:
1. Make sure the furnace blower is operating, the control
switch is on, and input voltage is correct.
2. Remove front door assembly panel.
3. Remove power pack access cover.
4. Check the high voltage contact board assembly(s) for
damage or carbon tracking.
NOTE: The cell contacts should be visually checked for
corrosion, excessive dirt build up, and electrical arc tracking
(carbon path from stainless steel spring to grounded metal). Clean
or replace as required.
5. Make connections from the high voltage probe to the
multimeter in accordance with the operator’s manual. The
meter should be set for reading DC voltage on the 20 volt
full scale.
6. Attach the high voltage probe ground lead to the cabinet.
While depressing the safety switch lever, touch the ionizer
